== LDAP Global Format Registry ==

=== About Global Format Registry ===

The Global Format Registry (GFR) serves as a main repository for file format and application information. As GFR is mainly for querying rather than updating data inside, the Lightweight Directory Access Protocol (LDAP) was chosen to base GFR.

Among various LDAP frameworks and platforms, we chose to use [[http://www.openldap.org|OpenLDAP]] as our server. For Java LDAP library, we are using [[http://developer.novell.com/ndk/jldap.htm|JLDAP from Novell]]. We also set up the [[http://freshmeat.net/projects/phpldapadmin|phpLDAPadmin]] to provide an administrative interface to our GFR.

You can see the LDAP admin interface at http://naradev05.umiacs.umd.edu/phpldapadmin/

Each leaf node under the node with ou=Applications represents an application whereas that under the node with ou=Formats is for a file format.

A leaf node has a set of attributes that have the detailed information on the object. Two example sets of attributes for an application node and a format node are as follows.
